Autonomous Cyber Defence Platform
Spharaka Sphere™ is an autonomous cyber defence platform that uses agentic AI to detect, investigate, reason about, and respond to cyber threats at machine speed.
What an autonomous cyber defence platform is
An autonomous cyber defence platform does not hand an analyst a queue of alerts to work through. It detects the event, gathers the context around it, reasons about what the evidence means, reaches a decision, and acts on that decision, with human oversight retained where it matters. The distinction from automation is the reasoning step: a scripted playbook executes a response somebody wrote in advance, while an autonomous platform decides what the response should be.
- Detection across endpoints, networks, cloud, identities and applications
- Investigation that assembles evidence rather than raising a ticket
- Reasoning over the whole environment, not one alert at a time
- Response executed at machine speed, with oversight where it counts
One platform, not a stitched-together stack
Spharaka Sphere unifies SIEM, SOAR, XDR, and EDR into a single intelligent platform that delivers what traditional systems cannot: complete visibility, automated intelligence, and machine-speed response across your entire digital infrastructure. Consolidating those tools removes the seams where context is lost between them.
- Seven AI-native capabilities: SIEM, SOAR, XDR, UEBA, EDR, CTI and autonomous threat hunting
- End-to-end visibility across the entire attack surface
- Automated intelligence and response at scale
- Cloud, on-premise and hybrid deployment
The technology underneath
The platform is built on two proprietary components. AuraXP™ is an agentic AI Cyber Brain that mirrors the decision-making of elite security analysts at machine speed and scale. SAGE™ is Spharaka's proprietary Cybersecurity SLM, developed by fine-tuning state-of-the-art open foundation models on Spharaka's cybersecurity datasets, reasoning frameworks and autonomous investigation technology.
- AuraXP™: 40+ AI agents operating as your virtual SOC team
- SAGE™: a cybersecurity-specific model rather than a general-purpose one
- Independent RAG for each customer environment
- Persistent Security Memory that retains organizational context
- No AI hallucinations by design, with full data sovereignty and isolation
Where the platform runs
The same autonomous defence extends across the enterprise estate and into industrial operations, with a surface built for each.
- Spharaka Sphere™ for enterprise IT security operations
- Spharaka EdgeProtect™ for continuous endpoint visibility, detection and rapid response
- Spharaka Signal™ for OT and ICS environments, through passive network analysis
- AirWatch™ for autonomous network observability across the estate
The security operations it carries out
Rather than licensing detection, correlation, orchestration and hunting as separate products, the platform performs them as one system that shares the same context.
- AI SOC: autonomous security operations end to end
- AI SIEM: log analytics, correlation and threat prioritization
- AI SOAR: dynamic playbooks, orchestration and autonomous response
- AI UEBA: user and entity behaviour analytics for insider threat
- Autonomous Threat Hunting: continuous hunts mapped to MITRE ATT&CK
What changes after deployment
Organizations deploying Spharaka experience immediate and measurable outcomes: reduced operational cost, faster response times, higher detection accuracy, and dramatically streamlined security operations.
Frequently asked questions
What is an autonomous cyber defence platform?
An autonomous cyber defence platform detects a threat, investigates it, reasons about what the evidence means, decides on a response and carries it out, without requiring an analyst at each step. Spharaka Sphere™ is an autonomous cyber defence platform that does this at machine speed, with human oversight retained for high-impact decisions.
How is autonomous cyber defence different from security automation?
Automation executes a response that somebody wrote in advance. A scripted playbook can only handle the situation it was written for. An autonomous platform reasons about what it is seeing and decides what the response should be, which is why it can handle threats nobody anticipated when the playbook was written.
Does an autonomous cyber defence platform replace SIEM, SOAR and XDR?
Yes. Spharaka Sphere unifies SIEM, SOAR, XDR, UEBA and EDR into a single intelligent platform, so those capabilities are performed by one system sharing the same context rather than by separately licensed tools passing data between them.
What does agentic AI mean in this context?
Agentic AI means the platform runs AI agents that can take actions and pursue an investigation, rather than only classifying or summarising. AuraXP™ operates more than 40 AI agents as a virtual SOC team, handling behavioural understanding, predictive threat modelling and real-time orchestration.
Why use a cybersecurity-specific model rather than a general-purpose LLM?
SAGE™ is a Cybersecurity SLM developed by fine-tuning open foundation models on Spharaka's own cybersecurity datasets, reasoning frameworks and investigation technology. It gives each customer an independent RAG, persistent security memory that retains organizational context, and full data sovereignty and isolation.
Can the platform be deployed on-premise or in a sovereign environment?
Yes. The platform supports cloud, on-premise and hybrid deployment, with an independent RAG per customer environment and full data sovereignty and isolation, which is what makes it suitable for regulated and critical-infrastructure operators.
Does autonomous cyber defence cover OT and industrial environments?
Yes. Spharaka Signal™ extends the platform into operational technology and ICS environments, delivering passive asset discovery, protocol-aware threat detection and industrial network visibility without interfering with industrial operations.
